BOX-COUCH HINGE.

SPECIFICATION forming part of Letters Patent N0. 758,530, dated April 26, 1904. Application filed July 7,1902. Serial No. 114,549. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES W. Games, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Box-Couch Hinges, of which the following is a specification. I

My invention .relates to improvements in hinges for box-couches, trunks, or other apparatus of this character, the object of my invention being to provide a hinge which will cause the top of the box-couch to move forward when it is raised, thereby avoiding the necessity of drawing the couch away from the wall in order to raise the top thereof.

The object of my invention is to provide a hinge of this character which shall be simple in construction and which can be very readily fitted to a box-couch without previous adjustment.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends, hereinafter fully specified, and particularly pointed out. in the claims.

In the accompanying drawings, Figure 1 is a vertical section taken close to the end of the box-couch, showing the same closed. Fig. 2 is a similar view showing the lid of the couch raised. Fig. 3 is a section of the end of the box-couch, showing an edge view of the hinge.

Referring to the drawings, 1 represents the body of thecouch, and 2 the lid thereof.

3 represents the bottom plate of the hinge, secured to the body of the couch by the screws 4, and 5 represents the top plate of the hinge, secured to the top of the couch by the screws 6. Said top plate is formed of a single piece of metal bent twice at a right angle, the upper portion? being secured on the outside of the top of the couch, the middle horizontal portion 8 being secured on the under side of the edge of said top, and the lower vertical portion 10 being provided for attachment thereto of the link connections with the bottom plate. Said link connections comprise a bar 12, connected, as shown at 13, with the rear lower corner of the top plate, and, as shown at 14, with the front end of the bottom plate.

Pivoted to said bar 14 is a bar 15, extending obliquely across the same, the front end of which is pivotally connected bya link 17 with the front lower corner of the top plate, as shown at raand the rear end of which is piv- 'otally' connected by a link 19 with the rear portion of the bottom plate, as shown at 20.

It will be seen that the top of the couch can only be raised-by opening the angle between the bar 15 and the link 17 If this angle be enlarged or opened, then the angle between the bar 15 and the link 19 must also be enlarged, and this will cause the bar 12 to swing forward on its pivot, thereby causingthe whole top to move forward, so that as the top of the couch is raised the rear portion thereof simultaneously moves forward, thus avoiding contacitl of the upper rear corner thereof with the wa An important advantage in the use of the hinge is the saving of time occupied in attaching the same, it being attached as quickly as r a common hinge and no adjustment for tha purpose being necessary.

I claim- 1. In ahinge, the combination of the top and bottom plates, the bar directly connecting said plates pivotally, the bar pivoted to said former bar, and links pivotally connecting the ends of said latter bar with said plates, substantially as described.

2. In ahinge, the combination of the top and bottom plates, the bar pivotally connected with the rear end of the top plate and with the front end of the bottom plate, the bar extending obliquely across and pivoted to the first-named bar, the link pivotally connecting the front end of said latter bar with the front end of the top plate, and the link pivotally connecting the rear end with'the bottom plate,

substantially as described.

3. The combination with a box and its lid, of an opening mechanism for said lid, having a rigid lever or arm, the ends of which are pivotally connected with said box and lid respectively, a second arm or lever pivotally connected with the lid at one side of the pivotal connection of said rigid arm or lever with said lid, a third arm or lever pivotally connected with the box, and a connecting means to which the free ends of said second and. third arms or levers are pivoted said connecting means being also pivoted to said rigid arm or lever.

4. The combination with a box and its lid, of a rigid lever pivoted at one end within the box and at the other end to said lid, a second arm or lever pivoted at one end to said lid at one side of the pivotal connection of said rigid arm or lever with said lid, a third arm or lever pivotally connected at its lower end with the box at one side of the pivotal connection of said rigid arm or lever with said box, and a link or lever pivoted to said second and third levers and to said rigid arm or lever at different places in its length.

5. A lid-opening mechanism having a rigid lever or arm provided at its upper end with means for attaching it pivotally to the lid and at its lower end provided with a pivot to engage a fixed support, and a system of levers, the upper end of one member of which is provided with means for pivotally attaching it to said lid and the lower end of another member of which is provided with means for pivotally attaching it to a fixed support, said system of levers also having a member which is pivoted to both members thereof before mentioned and is also pivoted to said rigid arm or lever, for the purposes set forth.

6. The combination with a box and its lid, of an opening mechanism for said lid, saidv opening mechanism having a rigid arm or lever the lower end of which is pivoted within ber having one of its ends pivotally connected with said lid in advance of the pivotal connection of said rigid arm or lever with said lid, another member pivotally connected, within the box to a fixed support, at one side of the lower end of said rigid arm or lever, and a third member pivotally connected to the free ends of the before-mentioned members and pivoted to said rigid arm or lever between the same.

7. In a lid-opening mechanism for boxcouches, the combination with a rigid arm or lever having means at its ends for pivotally connecting said ends with the box and lid respectively, asecond arm or lever having means at one end for pivotally connecting it with said lid, a third arm or lover having means at one end for pivotally connecting it with the box, said second and third arms or levers being arranged on opposite sides of said rigid arm or lever. and a link pivoted between its ends to said rigid arm or lever and having its ends pivoted to said second and third arms or levers.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.

CHARLES W. GROSS.
